WILLIAM MONROE CRANE, OF BALTIMORE, MARYLAND, ASSIGNOR OF ONE-HALF T0 J.

' FRANK FOX, 0]? BALTIMORE, MARYLAND.

nna'rm Specification of Letters Patent.

Application filed August 2, 1919. Serial No. 314,920.

' will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to beaters for use in beating eggs, whipped cream or any other substance, or combinations of substances which it is desired to change to a foamy consistency.

I attain this result by agitating the eggs or other substances and at the same time forcing. air through the body thereof.

In carrying out-my invention I make use of the instrumentah'ties illustrated in the accompanying drawings in which Figure 1 is a central section of my 1mproved beater.

. Fig. 2 is a plan view thereof with the cover omitted.

Fig. 3 is a perspective view of the dasher.

In the drawings 5 is the casing of my improved beater provided with the removable cover 6 and with the conical shaped bottom 7 the latter being soldered to the casing 5, or otherwise secured thereto. v r

The dasher 8 is also conical in form and preferably of the same angle as the bottom 7.

, The handle 9 is provided with wings 10-10 and the latter are soldered, or otherwise secured to the dasher 8. The handle 9 slides freel through a hole provided in the cover 6 an is provided on its top with the ring 11. The dasher 8 is provided near its edge with a plurality of'holes 12. There may be any desired number of holes similar to 12 but it is desirable that there be an imperforate space between the innermost row of holes and the point of the dasher. The urpose of this imperforate portion will be ater explained.

' Patented Dec. 23, 1919.

i The operation of my improved be'a ter isas follows:

The cover 6 and dasher 8 are removed and the eggs or other substances are introduced within the" casing 5. The dasher and cover are then placed in position in the casing as stances are squirted through the holes 12 and the air entrained in theimperforate portion of the dasher is forced through the eggs or other substances and squirted through the holes 12. v

. The ring 11 is then moved upwardly and the dasher 8 acting like the iston of a pump a sucks the eggs or other so stances and air through the holes 12.

It is to be understood that the dasher 8 is to be reciprocated rapidly and the squirting and sucking of the eggs or other substances through the holes 12 combined with the interaction of the air rapidly changes them to a foamy consistency;

My improved beater may also be used for mixing liquids.

Thus it will be seen that I provide a simple, cheap and eflicient beater in which many "changes may be made without departing from the-spiritof my invention.

I claim In a beater, the combination with a hollow cylinder, of a bottom havinga conical surface directly joining the inner surface of said cylinder, a conical dasher reciprocating in said cylinder, the edges of said dasher having iston-tight engagement with the inner sur ace of said cylinder, the center of said dasher being imperforate to form an air dome, and perforations insaid dasher adjacent said edges.

In testimony whereof, I aflix my signature.

WILLIAM MONROE CRANE.
